This appears to be a "Shoujo Club Prize Bookmark" (Shoujo Club Shou-shiori), a supplement or related item from the pre-war Japanese publication "Shoujo Club." "Shoujo Club" was a magazine for girls published by Dai-Nippon Yuben-kai Kodansha (present-day Kodansha). These bookmarks seem to have been created as commemorative prizes for readers and as promotional items to "increase the number of Shoujo Club readers." The illustrations of the women depicted reflect the modern girl image of the time. The word "shiori" (bookmark) is generally written as "しおり" in modern Japanese, but this spelling reflects the style of the time. - Title: Shoujo Club Prize Bookmark - Design: Art Deco style illustrations - Contents: Illustration card set - Quantity: Set of 5 - Condition: Shows signs of aging Thank you for viewing.
